Burke Brise Soleil, Milwaukee Art Museum

The Burke Brise Soleil is a bird-like addition to the Milwaukee Art Museum, designed by Santiago Calatrava. It‘s a moveable, wing-like sunscreen perched atop the museum’s vaulted Windhover Hall. It has a wingspan comparable to that of a Boeing 747-400 – spreading 217 feet at its widest point - but to prevent damage to the building, two ultrasonic wind sensors automatically close the wings if the wind reaches 23 miles per hour or higher. It controls both temperature and light in the structure.
